METHOD AND MEANS OF PRODUCING MULTICOLORED PHOTOGRAPHS.

To all whom it may concern:

Be it known that I, Isn)oR Krrsnn, a citizen of the United States,residing at Philadelphia, in the .county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMethods and Means of Producing Multicolored Photographs, of which thefollowing is a specification. A

The object of this invention is to'provide an improved method and meansof producing multi-colored photographs, whereby it is possible to make anegative photograph of agiven scene or object in different colors withthe aid of one carrier or holder.

' Having made a negative, another object of the invention isto providefurther steps "in the improved process, whereby it is possible from saidnegative to make as many positive prints as may be required withoutimit.

A still further object is to provide an improved product, which productmay be used with but slight. alteration in'ipreference to the commonlyknown opaque print of a blackand-white negative, or as atransparency-for A .limtern-slides and the like.

More than one method of color-photography that has been developed thusfar comprises the formation of a set of monochrome transparencies, eachof a fundamental color and embodying a positive photograph of that partof a given object or scene having "a 00 until every ob ect upon "eachtransparency matches up as nearly as possible with the cies are t en surimposed one upon another corresponding objects upon the othertransparencies, or, in other'words, so that each 40 set oftransparencies registers perfectly or with the least possibledisplacement.

However, all those who have made photo-\ graphs by certain of theprocesses which are 'carried'out alongthe line -mentioned haveexperienced an almost insurmountable obstacle in their inability toexactly register the plurality of transparencies, for, while the oneoftenin yellow is usually ratherwell defined, that probably in red ismuch less so, and the one generally tinted blue is in' most instance sovaguely definedas to make it almost an absolute impossibility to findthe exact position which it should bear with encies.

Bearing these objects in'mi-nd, the invenich was origtion' comprisesdetails of construction and operation hereinafter clearly described inthe following spccificati0n, whenread in conjunction with theaccompanying draw-i ings, in which Figure 1' is atop'plan view of theprincipal elements of a camera such as.

8 is a similar view showing the positive transparency-unit mounted as anordinary opaque print. I I

Referring to the drawings, a camera is shown comprising a base 1, uponwhich is mounted the usual frame 2, from the forward open side of whichprojects the usual bellows 3, provlded upon its outermost restrictedportion with the usual lens-holder or casing 4, said last-named casingbeing carried adjustably vertically by a support 5, extending upwardlyfrom a slide 6 adapted to reciprocate for the longitudinal extension ofsaid bellows upon a track 7. The

essential difference of this camera from those commonly in use res desin the factv that the frame 2 is provided upon the rear ,thereof with asubstantially rectangular box or chamber 8, having the length of itsside walls 99 substantially equal to the width of the device across thereal-most wall 10. v

The said inclosure 8 may, if desired, be

. separable from the remainder of the camera in order that the formermay be readily dismounted from the latter and carried to a dark room,where it is obviously most conveniently loaded with a sensitive negativetransparency-unit, a .dark slide or trap 8 being provided to close saidbox when thus dismounted. As shown schematically in Fig. 1, thenegative-unit comprises a central section 11 positioned parallel with respect to the wall 10, a forwardly laterally positioned section12parallel with respect to the wall 9, and asecond and similar forwardlyextending laterally positioned section 13 positioned parallel withrespect to the wall 9'.

Primarily, it is to be noted that in general the present processprovides for the consecutive exposure of each of. the lateral andcentral sections of the negativeunit to the rays of light from theobject to be photographed as said rays pass through the lens-holder 4.

T 0 this end, it is not of vital importance what order is employed inthe exposure of these various negative-unit sections :Thus, an exposureupon the central section may be made with .the apparatus positionedexactly as shown in Fig. 1, after which the negative section 12 may bemoved, by suitable means connected to the knurled wheel 12", about thecenter 12 into'the dot-and-dash position parallel with and abuttingagainst the section 11. An exposure being made upon the section 12 inthis position, said section is removed, by revolving the said wheelinthe reverse direction, to its position adjacent to the said wall 9 ofthe device. and the negative section 13 is shifted about the center of13, bymeans connected to the knurled wheel I 13", into the dot-and-dashposition just previously occupied by the section 12, in which position athird exposure is made, this time upon the section 13.

Preferable in practice and possibly necessitating the least number ofmovements during the exposure of a complete negative-unit, the box 8 isloaded with either of the sections 12 or 13 inthe dot-and-dash position,in which position an exposure thereof is I made, after which the exposedend sectionof the negative-unit is shifted to one side, an

exposure made of the central section of the slightly smaller than thecorresponding number ofv pan-chromatically sensitized carrier sections22?, 22', and 22 mounted upon said sheet and secured thereto centrallywith relation to the respective apertures 21. The mat 20 is furthermoreprovided, centrally positioned. between the neighboring apertures 21,wit-h transversely extending elongated slots 23, from the opposite endsof which to the neighboring edges of said sheet extend score-marks 2tfora purpose hereinafter described. i.

yEach of the carrier sections 22 22 and 22 is coated upon one facewit-ha panchromatic emulsion. The 'carrier sections 22. a-nd'22 arefurthermore provided upon A mat 20-of non-elastic material is thesurface thus sensitized with opaque coatings as indicated, while upontheir opposite faces they are respectively coated with green and bluecoloring for the purpose of forming screens of those partlcular colors.

The intermediate carrier section 22" has a colorscreen of red upon thesurface of the emulsion and is without a coating of any sort upon itsopposite surface. These respective color-screens and opaque coats arereadily removable after exposure of. the units to light, either beforeor during the process of developing andfixing of the emulsion layerscarried by said units,

The negative unitthus formed is inserted into the box portion 8 of thecamera, as.

shown in Fig. 1, and three closely consecutive exposures made by any ofthe usual.

methodsof intermittently opening and clos-- ing the camera orifice inthe lens-casing 4 and as hereinbefore described. With the negative-unit.preferably in place; as described, light rays, permitted to eiiter thecamera through the usual lens for a short period of time, pass throughthe colorscreen and carrier of, and act upon the emulsion upon, theopposite side of the carrier section 22* in the dot-and-dash position,but cannot contlnue past the opaque coating and afiect the emulsion uponthe carrier carrier section is shifted or pivotably swung out of thedot-and-dash posit-ion, immediately after which light rays are permittedto section 22 after which this first-exposed case passing through thecolor-screen car-.

ried thereby and acting upon the emulsion surface of the saidcarriersection. Similarly, after the carrier section 22"is thus exposed,carrier section 22 is shifted into the dot-and-dash position andexposed, light rays passing through the color-screen and transparentcarrier before acting upon the emulsion carried thereby and beingstopped by the opaque coating from continuing onward and'afiecting theemulsion of the carrier section 22'.

\ pose the chemicals comprising the emulsion The negative thus exposedeither has the color-screens and opaque coatlngs first dissolved orotherwise removed therefrom as before mentioned, after which theemulsion coatings are developedand fixed in the usual manner andpermitted to dry. It should be remembered that thus far, and in factcontinuously hereafter, the negative-unit comprising the mat'20 andtransparent carrier section'attached thereto are at no time disunited,although they may be shifted in angular position with respect to oneanother by virtue of their relative' pivotal connections.

To print from the negative thus produced, a frame is provided comprisingabase 30, from which extend-upwardly, spaced, parallel bars 31, inlength, thickness and distance between centers being exactly equal tothe slots 23 ofthenegative-mat 20. Upon this base is placed atransparent carrier 32, par-' ticularly illustrated in Figs 5 and 6, the

same being provided with spaced parallel elongated slots 33 "adapted toreceive the bars 31 of the printing frame, while in alinement with saidslots are. score-marks 34, upon which lines the carr ier isllater to befolded, said carrier also being providedv upon its upper surface "with acoating of chromated gelatin 35. Upon this positive,

sensitized-carrier is placed face downward the previously exposednegativemnit hereinbefore described and as clearly shown'in Fig. 6.

With the negative and chromated blankv 1n the positions thus shown, thecombination is exposed to lightso that rays of the same pass through thenegative and decomnpon the chromated carrier. Removin both of theseelements from the printing rame,

series of spaced. apertures, incombination 120 the'chromatedcarrier,printed on by means of the well-known process, is found tocomprise three distinct photographic impressions which, arecomplementary as to light and dark portions to those carried by thenegative-mat. The printed positive is then treated in the usual mannerto remove the unaffected gelatin. j V

It is now possible to tint or stain the three respective photographicimpressions of the positive by means of colors which are re- .productillustrated by Fig., 8 is the equivalent of and closely resembles theusual pho- .through which the original negatives-have .105

' Patent of the United States is positive section 32 corresponding 'with"(green) negative carrier section 22 is stained red, the centralpositive section corresponding with (red) negativ'ecarrier sect'ion 22is stained blue, and the OSltlVG sec- -tion 32 corresponding with lue)negative carrier section 22 is stained yellow, the coloring in each ofthese instances adhering only'to those parts of the sensitized positivesurface on which the emulsion has been affected by'light, and also tothe extentto which said emulsion has been thus acted upon. I e p Theresulting positive then simply folded upon the score-lines 34, so thatthe result as illustrated by the cross-section in Fig. 7 comprises aphotograph adapted to be mounted on a suitable base such as a matv 37,which in reality maybe one of-the stiff papers or boards used in mountinphotographic prints. Said mat has a sur ace possessinghigh reflectivepowers, so that the tographic print upon white paper, except for thefact that the reproduction possesses.

natural colors of the original object. It is obvious that instead ofprintingon gelatin from the negative directly, a transparent positivemay first be made from-said negative, and the chromated gelatin printsmay then be produced'with the aid of such .pos1- tive. In that case, itis suggested .to tint the different sections of. the gelatin printswith, colors substantially the same as the filters been taken, and ,thecomplete photograph maybe mounted on a suitable transparent. materialforlantern-slides or to be viewed as transparencies.
